SPARK-=ARRESTFER.

SPECIFICATION forming part of Letters Patent No. 309,663, dated December 23,1884.

Applicaiion filed April 11, 1884.

(X model.)

.To all whom it may concern.-

Be it known that I, J AMES A. STOUT, of Belleville, in the county of St. Clair and State of Illinois, have invented certain new and useful Improvements in Spark-Arrestcrs, of which the following is a full, clear, and exact description.

This invention consists in a novel construction of smoke-stack for traction and other like engines or locomotives, having for its object the prevention ofconflagrations from escaping sparks or burning particles of fuel, the insuring of a good or perfect draft, and the adapting of the stack to different kinds of fuel; and it comprises certain combinations of parts, including an inner uptake and water-receptacle outside of the same, an outer pipe or duct arranged to produce a downdraft into and up through the water receptacle, and a hinged or raising and lowering screen cover at top of sai d outer pipe, and inner spark-deflector arranged to move up and down with it, substantially as hereinafter shown and described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1. represents a vertical section of the boiler of the engine in part, with a steamdome mounted thereon, having a smokcpipe, forming a lower continuation of the chimney, passing therethrough, and the improved sn'iokestack or chimney hinged to said dome. Fig. 2 is a horizontal section on the line a: m in Fig. 1. r

A is the steam-boiler in part, and 13 the steam-dome, having a pipe, Z), up through it for passage of the smoke, and which virtually forms a lower continuation of the chimney, and which is inclosed by the outer casing of the dome, leaving an annular space, 0, between them for the circulation and superheating of the steam. Hinged to this dome B at it top, on one side, as at (Z, by a base-ring, c, is the primary or inner flue, O, of the chimney proper, in line, when the chimney is shut down upon the dome, with the pipe I), of which it forms an upward continuation. Outside of this pipe or flue C is another pipe or flue, D, of sufficient capacity to leave an annular space,f, between said pi pcs,

and arranged so as to inclose the upper portion of the inner pipe, 0, forming an outer casing thereto, and to extend downward to inclose a large or greater portion of said pipe. The outer casing or duct, D, is open at its bottom and dips into or enters a water-receptacle, E, at and surrounding the lower portion of the pipe 0, and is provided at it top with a funnel-cap or flaring extension, 9, covered by a wire screen, h, that has attached to it by bolts 1' t, and serves to carry within it, a spark-deflector, G, arranged over the upper end of the pipe 0. The pipe 1), with its adjuncts, may be carried by the inner pipe,G, through means of bolts 7;: In, or otherwise, and the wire-screen cover h is hinged, as at Z, on one side of the flaring top 9 of the pipe 1), and is made capable of being raised, as .shown by dotted lines, or lowered, as shown by full lines, Fig. 1, by an arm or lever, m, attached at its upper end to the screen cover h, and engaging with a screw or other fastening, n, on the flaring top of the pipe 1). The deflector G serves to throw the sparks and any escaping particles of fuel into the water-receptacles E,where they are quenched and collected,while smoke passing down through the space f is free to escape through the exposed or open top of the said receptacle E, in addition to the up or direct draft for the smoke through the flaring top {1 of the pipe D, thus affording two outlets for escape of the smoke.

This in'lprovcd stack is adapted to either wood or coal burning engines. lVhen using wood, and the sparks or escaping burning particlcs are numerous, then the hinged screen cover 71 and the deflector (iare kept down or closed; but when using bituminous coal, for instance, which produces soot that is liable to close up the meshes of the screen h, said screen 71 and deflector G- may be raised to give perfect freedom to the draft without risk or dangcr by reason of their being no tendency of sparks to be blown or carried off. The raising of the screen cover 71 and deflector (1-, as shown by dotted lines, Fig. 1, will also be found advantageous when starting a fire by giving a f rec natural draft before the engine commences ll'll'lllillg and creates an artificial one.

The receptacle may be first supplied with Water byhand or otherwise, but afterward may 'be kept up or replenished by condensation of the escaping steam within the stack.

The screen cover h may be more or less raised, as -required, to suit different kinds or qualities of fuel, and be held in its adjusted position by the screw or other fastening, n, on the arm or lever m.

It should here be observed that it is important that the upper margin of the water-receptacle E should be above the lower end of the outer smoke tube or casing, D, so as to compel and secure the deposit of sparks in the water and prevent them from passing out over the top of the Water-receptacle.

The two outlets for escape of the smoke, which this construction of stack provides for, is an a1l-important feature of this invention.

Instead of the smoke pipe or stack being connected with a steam-dome, as described, it might be connected with the smoke-saddle or be attached directly to the boiler, and where a hinged base-ring, e, is used said ring may be attached to the boiler (which may be of any suitable construction) or to the smoke-saddle, irrespective of the dome. Furthermore, the sparkdeflector may be of any other suitable shape than that here shown, and, if desired, may be permanently attached to the smoke-pipe O, instead of the screen-cover, thus making it a stationaryinstead of an adjustable deflector.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent 1. The combination, with the inner smokepipe, 0, and open-top Water-receptacle E, of 5 the outer pipe or casing, D, the deflector G, held above the smoke-pipe O, and the screen cover h, secured to the top of outer pipe, D,

above the deflector G, substantially as specified.

2. The opening and closing screen cover h, and spark-deflector G, held below the same over the smoke-pipe, in combination with the outer casing or pipe, D, to which said screen cover is hinged, the inner smoke-pipe, G, and the water-receptacle E, essentially as shown and described, and for the purposes herein set forth.

3. A hinged smoke-stack consisting of the' JAMES ANDREW STOUT.
